Trying to find out what is the best way to max out my spell damage with my paladin. Currently I have only about 770 with about 23% crit and I have 1900 healing. I have a couple of +22 healing and +8 spell damage Gems and the rest are +13 healing.

I was thinking of using gear just for healing and gear just for Spell damage pvp since I have a few different items that give me a greater crit chance for my spells but I don't have any cut gems to socket them with. Is it a good plan to use nothing but spell damage gems on all of my sockets for my pvp gear and just rely on enchants or something to raise my spell crit? The other shockadins I see always use the T6 holy armor set but the shoulders that drop in hyjal seem to be better for spell crit and damage...but howcome I never see Don or Edoly wearing them? I would hate to use up gems on those shoulders if for some reason the T6 shoulders were better, but looking at the stats it doesn't seem that way.
